boost advice

[kingkraka]

I have a 1997 GS-T its all stock but id like to get about 16 psi of boost. From what im told the car come with 11psi stock upping the boost that much do i need to upgrade to fuel system or change the timing? Any advice is welcome.

No that it is not necessary to upgrade the fuel system or mess with timing!
You should be somewhat safe just turning it up, not that i recommend that.
Tech Guide - DSMtuners

Best thing to do is follow the upgrade path on here, and do you upgrades right!

I don't believe the t25 would be that much more efficient after 16psi, its a tiny turbo.
The only thing that i highly recommend for tuning up the boost to 16psi, is watching for knock and proper A/F ratios!! Next step would be tuning software and fuel upgrades.. IMO But again its on a stock t25!!

Read the upgrade path, as stated.

And don't shoot for a certain boost level, this is dumb and will help you blow your car up - shoot for a power level.

Just set it to 15psi for the time being and be done with it til you get the proper mods to turn up the boost, along with a bigger more efficiant turbo..

as skatershawn and Absit have said read through the upgrade path and don't shoot for a specified boost level. That being said it is possible to run that level on a mostly stock car but you must be able to accurately measure air fuel ratios and knock to be certain you are in a safe range.

what i would do is buy something to tune with (safc, ecmlink) and take it to a speed shop and have them tune it for you. You can also buy a wideband and learn how to tune it yourself.

iv got a bigger turbo its a t3/t4 63mm trim and bov just yet to put it on. this isnt my first turbo car just frist STOCK turbo car. bout 60hp more wold be nice. i know i had to do alot of upgrades on my other car just to run 8 psi.

 

[Bud92gsx]

Your going to need a few more mods in order to run that big of turbo at more than 15 psi..If you install it now It isn't going to help you much.

 

[GsXdSmKingGsX]

Why would you install a big turbo on a car with a stock fuel system setup and no tuning device or even wideband? BAD JUJU

 

[Bud92gsx]

That's what I just said Josh..

 

[crusada]

I agree bad juju is right what turbo car were you running 8psi on and had fuel mods had to be a honda and again as josh would say bad juju dont even compare a dsm to a honda they are totally different animals from alot of cars.

 

[Bud92gsx]

You can run b16 hondas on old dsm parts..My buddy has a litle civic hatch running 10psi on a stock b16..Don't ask me how he has not blown it up yet, cause I asked him the same thing..

 

[GsXdSmKingGsX]

That's what I just said Josh..

I didnt "say" anything. I was asking him a question.

I agree bad juju is right what turbo car were you running 8psi on and had fuel mods had to be a honda and again as josh would say bad juju dont even compare a dsm to a honda they are totally different animals from alot of cars.

Where did I compare a DSM to a Honda?

 

[crusada]

no no not you josh i was referring to the guy that posted it. when he was saying he had big mods to run 8 psi and hes saying hes had turbo cars before. thats what i was refering to i figured he was trying to compare owning a turbo honda to a dsm

 

[Bud92gsx]

You didn't say anything about a honda..I sounded like a boosted honda in post #7, that's where he got it from..

 

[crusada]

exactly bud thats what i did get it from only 8psi and having to mod alot sounds like a boosted honda

 

[kingkraka]

i had a 97 ford probe GT on 8 psi not a damn honda.

it was a 2gen probe GT i had put a 255 walbro fuel pump, 12:1 vortech fmu, and 290cc injectors just to run 8psi but it could of been worse it could of been a damn honda

 

[jb2zero0six5]

290cc are upgrades? DAMN.
